3. Major Error Messages and their Causes
The integrated monitoring system distinguishes between minor and major errors; major
error messages (e.g. malfunctions of the encoders, of the drives or data processing errors)
blink. In the case of gross errors, the control opens the contact "Control Ready for
Operation" which causes an emergency stop of the machine tool.
By switching off the main switch or pressing
END
, the "emergency stop" state can be
reset, provided that the error cause has been eliminated.
